What is MIIDEL?

MIIDEL is a system that highlights changes in drawings and documents with color to quickly identify modifications.

As shown in the image below, the changes in the documents on the left and right are not easily noticeable at a glance.

Troubleshooting and Frequently Asked Questions (Launcher)

Q1. I want to use MIIDEL on a 32-bit computer.

A. MIIDEL has been a 64-bit only system since version 5, so please use it in a 64-bit environment.

Q2. I was able to use MIIDEL until recently, but suddenly I can’t log in. What should I do?

A. Please delete the folder at “C:\Users[Your Username]\AppData\Roaming\Miidel8”. Performing this operation will also delete the license information, so you will need to re-enter your license information. Please prepare the correct license information before proceeding.

Q13. I received a message saying the offline usage period has expired. What should I do?

A. MIIDEL needs to check the license status while online. We apologize for the inconvenience, but please register again while online.

Q14. I am getting an "Exceeded maximum usage limit" error while using MIIDEL. How should I handle this?

A. If MIIDEL did not close properly while being used, the usage state may continue for 30 minutes. Therefore, this message may appear even when there are no other users. We kindly ask you to check the number of currently active and running users again, and then attempt the operation once more.

Q15. I don't know what to enter for the address and port. Can you please help me?

A. This is where you should enter the address and port number of the proxy server that your company is using. Additionally, you may need to enter user authentication information for the proxy server, if necessary. Furthermore, access to api.miidel.com will also be required. Please confirm the specific input details and whether access to api.miidel.com is permitted with your system administrator.

Q16. After changing the proxy server settings, MIIDEL shows as offline despite being online, and the communication test fails. How should I address this?

A. First, please check the settings you configured in MIIDEL. If that does not resolve the issue, please delete the folder at “C:\Users[Your Username]\AppData\Roaming\Miidel8”. However, please note that performing this operation will also delete the license information, so you will need to re-enter your license information. Please prepare the correct license information before proceeding.

Q17. What should I do regarding license transfer when I update MIIDEL or change my computer?

A. When transferring a license, you can deactivate it on your old computer and then install MIIDEL anew on your new computer to register it. Depending on the version of MIIDEL, it may not automatically transfer the license. Specifically, direct transfers from MIIDEL5 to 6 or from MIIDEL5 to 7 are not possible. However, automatic transfer from MIIDEL6 to 7 is possible. For floating licenses, after deactivating the corresponding license from the management panel, you can register the license on the new computer to use it again.

Correction of Comparison Results

This feature is used when aligning distorted items such as scan images or when layout changes make it difficult to identify differences just by overlaying.

 

1. Automatic Correction

1-1. Distortion Correction

Automatically adjusts distorted scan images or images of different sizes to align with the modified image, making it easier to identify changes.

When performing the correction process, you can set a match rate threshold as the minimum match rate.

../images/13/0.png

(1) Click the "Correction Selection" button.

(2) Next, specify the match rate threshold. Click the settings button and select from the dropdown list.
(It is recommended to set between 70-80% for scan data or photos, and 100% for electronic data within the range of 50%-100%.)

(3) In the correction selection screen, choose "Automatic - Distortion Correction" and click the OK button.

  • To apply this to all pages after the current display page, turn on the option for applying to all pages.  

1-2. Layout Correction

Automatically decomposes parts within the image and overlays similar parts for correction.

  • Note on processing time: Layout correction may require relatively more processing time. Pages containing a lot of text tend to take longer to process compared to pages mainly containing images, and processing time increases with larger paper sizes.

../images/13/1.png

(1) Click the "Correction Selection" button.

(2) In the correction selection screen, select "Automatic - Layout Correction" and click the OK button.

  • To apply this to all pages after the current display page, turn on the option for applying to all pages.  

2. Semi-Automatic Correction

2-1. Three-Point Correction

Used for comparisons between completely different-looking pages, such as structural diagrams and design drawings, or drawings and photos.

By correcting images based on specific three points within the images, it becomes easier to identify changes.

../images/13/2.png

(1) Click the "Correction Selection" button on the screen.

(2) In the correction selection screen, click "Semi-Automatic - Three-Point Correction" and click the OK button. This will display the three-point correction settings screen.

../images/13/3.png

(3) On this screen, set the three reference points for both the before and after images.
Drag and drop the three points (red, blue, green) from the before image to their respective reference positions.

* You can adjust the zoom factor from 2 to 8 times during the drag-and-drop process using the magnifying glass option.

../images/13/4.png

(4) Switch the upper right bar to "After Changes" to display the modified image.

(5) Similarly, move the three points in the modified image. Finally, click the OK button to execute the three-point correction.

 

2-2. Layout Correction

By manually specifying parts on the page in advance, it makes it easier to find changes by automatically overlaying similar parts.

../images/13/5.png

(1) Click the "Correction Selection" button on the screen.

(2) In the correction selection screen, select "Semi-Automatic - Layout Correction" and click the OK button.
This will display the layout selection screen.

(3) On this screen, set the reference parts.

Troubleshooting / Frequently Asked Questions (MIIDEL)

Q3. MIIDEL crashes when I try to display high-resolution TIFF or PDF files.

A. Opening high-resolution TIFF or PDF files with a large number of pixels can make the program unstable. MIIDEL processes each drawing as a single image, so it may take a considerable amount of time. In such cases, please use a lower resolution. It is recommended to use standard resolution when creating PDF data or scanning from a multifunction printer.

Q4. When loading TIFF images or PDF images, an error message appears: "The page size exceeds the loadable limit. Please try lowering the DPI or loading in grayscale." What is the supported maximum size?

A. The supported maximum size is up to 2^30 [px]. If you exceed this size, you may receive an error message. If this happens, we apologize for the inconvenience, but please try reducing the resolution or loading in grayscale mode.

Q5. I want to load a PDF, but I am encountering an error and cannot load it. What should I do?

A. There may be an issue with the PDF editing software you are using. If there is data that cannot be loaded, we kindly ask you to re-PDF the document using "Microsoft Print to PDF," which is standard on Windows, or try using the latest version of MIIDEL.

Q6. What kind of problems might arise when trying to compare high-resolution or oversized data?

A. The processing speed may slow down, causing problems or drastically delayed operations in the following processes:

  • There may be instances where dragging to move (panning) is not possible.
  • Distortion correction, layer correction, and other correction functions can take about one hour depending on the computer's specifications.

Q7. What type of data processes quickly during distortion and layer correction, and what type processes slowly?

A.

[Fast Comparison Data]

  • Drawings and documents with mainly lines
  • Data with small paper sizes such as A4
  • Data with many blank areas
  • ⚠️ Even large-format drawings like 30m × 5m can process quickly if they have many blank areas and are line-based.
  • ⚠️ Performing comparisons on PCs with high CPU processing power and large memory will speed up processing.

[Slow Comparison Data]

  • Data scanned at high resolution
  • Drawings with a lot of text
  • Data with a large image size per page
  • ⚠️ If the computer’s CPU is slow and has only 2-8GB of memory, and the storage is like HDD, processing may take longer, or the data that can be compared may become smaller.

Q8. How long does the comparison process take?

A. The processing time varies greatly depending on the CPU and OS settings of the computer being used, as well as the usage conditions. As a guideline, please see the following:

  • For Intel Core i7 1185G7
Task Time
Loading 15 pages of A3 at 72 dpi 4 seconds
Comparison processing above 3 seconds
Loading 15 pages of A3 at 192 dpi 14 seconds
Comparison processing above 13 seconds
Distortion correction for 1 page of A3 at 192 dpi 6 seconds
Layer correction (alignment of elements) for 1 page of A3 at 192 dpi 18 seconds

Q9. Even after applying layout correction, I cannot compare successfully.

A. If there was only one part before the change, but there are multiple parts after the change, or if similar parts appear multiple times both before and after, automatic correction cannot be performed, leading to comparison failure. Scanned data with a lot of text smudging or line smudging, as well as data with extreme size differences, may also prevent partial correction. When performing partial correction, if the spacing of the selected range is different, it may be judged as separate items, making automatic correction impossible. In such cases, please select separate ranges as follows:

  • Narrow spacing

../images/15/0.png

  • Wide spacing

../images/15/1.png

Q10. Antivirus software is quarantining files needed for MIIDEL to run.

A. Real-time protection may isolate files that could cause unknown issues, but in this case, you will need to restore the quarantined files and add them to the safe list.

Q11. There have been reports of issues where security software that automatically encrypts saved files has encrypted files necessary for MIIDEL to run, preventing it from starting.

A. Please either disable the encryption settings or install MIIDEL in a folder that is not encrypted, and similarly, please use data files and saved files in an unencrypted location.

Q12. If the MIIDEL interface appears larger than the screen size, preventing normal operation, what settings should I adjust?

A. For MIIDEL's display settings, it is recommended to set the "Scale and Layout" in the "Display" settings to 150% or less. If it exceeds 150%, the interface may not display correctly.

Q18. Is it possible to change the default settings for comparison processes? Will the changes be reflected in the next execution?

A. Each setting can only be changed by operating MIIDEL on the client PC. Additionally, the only parameters stored for the comparison process are "Loading Resolution," "Color Display of Comparison Results," and "Settings for Automatic Sorting."

Q19. How should I understand the "Resolution when converting from DocuWorks" and "Resolution settings when loading new" on the settings screen?

A. When converting from DocuWorks at a resolution of 600 dpi, if the "New Load Resolution Setting" is set to 300 dpi, this means that "MIIDEL is comparing DocuWorks data after converting to a format that can be compared at 600 dpi, and then re-importing at 300 dpi for comparison."

Q20. I want to switch the computer that uses MIIDEL. What should I do?

A. You can log out from the client application and perform license activation on a different computer. For details, please refer to the "License Activation / Login" page in this manual. *License switching is only possible for node-locked licenses, and can be done once a month.

Q21. If I have not changed the model shape but reduced the layout size (from 1:1 to 1:2), is there a function to manually toggle between detecting this change as a "difference" and "not detecting it as a shape change"?

A. If the layout is changed, you will need to either use "Layer Correction" to automatically detect the change in position or use "Cropping" to manually adjust the position. If scaling is involved, it will be necessary to use the cropping parts scale function that is planned for upcoming implementation to match the size.

Q22. If I use PDF data directly converted from CAD, and also paper scans (PDF data) or PDF data directly converted from CAD, will the comparison results be the same? (Is it possible to correct the minor misalignment of paper scans so that they yield the same results?)

A. There may be text cut-offs or line cut-offs that are detected as differences when scanning paper drawings. Minor misalignments of paper scans can be adjusted using "Shift Correction" or "Line Width Change."

Q23. Are there differences in comparison results based on file format?

A. Differences in the results do not occur based on file format. However, differences may arise when converting from CAD data to PDF or TIFF, so subtle aspects (such as text or shape edge blurring) may be detected as differences. These can be handled as unchanged using the shift correction feature.

Q24. What is the range for detecting minor misalignments? Is it possible to set the detection range?

A. The detection range can be set from 0 to 3px using "Shift Correction."

Q25. Do differences in line types or line width changes get recognized as differences? Is it possible to configure it so that they are not recognized as differences?

A. The detection range can be set from 0 to 3px using "Shift Correction."

Q26. Can comparison results be output in formats like PDF or HTML, or can they only be viewed on the application?

A. Comparison results can be output as PDF files.

Q27. Is a license required to view files output after comparison within the application as well?

A. A license is also required to view within MIIDEL.

Q28. Can DocuWorks files be loaded?

A. MIIDEL can open DocuWorks files; however, the following conditions must be met.

  • To open DocuWorks files, you must have DocuWorks provided by Fujifilm Business Innovation installed.
  • MIIDEL only supports file loading with the latest version of DocuWorks; therefore, please always use the latest version when using DocuWorks.
  • DocuWorks Viewer Light does not support file loading. The full version of DocuWorks is required.
